Antiques Roadshow

PBS | 9:00 pm

"Welcome to New York" … it's not only the title of a Taylor Swift song, but also the underlying greeting of this new "Vintage" episode that takes the series back to the Big Apple. The vintage aspect comes from a reassessment of items first seen on the show 15 years earlier — and that decade-and-a-half has been particularly kind to one item, since its value has doubled. A 1968 letter from Robert F. Kennedy is featured. Mark L. Walberg is the host.
